Recommendation Toilet Water Saving Tips
Save water consumption through every day behaviors of individuals
Palestine has the possibility of the use of solar energy.

Recommendation 1. Check faucets and pipes for leaks
2. Check your toilets for leaks
Install water-saving shower heads and low-flow faucet aerators
3. Use your dishwasher and clothes washer for only full loads
